4 SECTION I GENERAL DESCRIPTION -. GENERAL. The CommCenter, Model 00MB Series D, is a digital playback device that is capable of generating up to six different prerecorded voice messages, melodies, tones and/or signals. This central control device interfaces with any decentralized or centrally amplified system. The CommCenter can control signal lines to Federal Signal SelecTone Models 00GC, 00GCX, 00X, 0GC, 0GCX, 0X, and 0GC speaker/amplifiers. It can also interface with any SelecTone Control Unit, Models 00VSC- or 00SCW-. It can directly drive speakers designed for rms line operation. It can also provide a Vp-p audio signal, and can be used as a remote audio input for a public address sound system. Using the 00MB s cascading function, CommCenters can be linked together to provide a system with the capability of more than six messages. TE The CommCenter accepts messages stored on ICs and pluggable circuit boards. Both are referred to as message chips in this manual. The messages stored on pluggable circuit boards will operate on all Series B, Series C, and Series D Models. The Series D CommCenters use a different storage IC than the Series A, Series B, and Series C. These ICs cannot be interchanged between Series A, Series, B, and Series C models. Make sure to specify which series CommCenter you have before ordering any additional messages. The CommCenter is intended to be installed in indoor (NEMA ) or other protected installations only. It can be mounted on any horizontal or vertical surface using #0 screws, appropriate for the type of mounting surface material, and the four mounting holes in the 00MB s housing (see figure -). The CommCenter can be used for a variety of prioritized signaling purposes, such as indicating the status of a machine or process, background messages, evacuation, alarm, start and dismissal, and other audible notification applications. The system can be automated if external (customer-supplied) devices such as programmable controllers, heat detectors, switches or program clocks are connected to the remote inputs. This product is not listed for fire use. A CommCenter plays and amplifies messages through signal lines to the remote SelecTone devices in the system. To connect the SelecTone speaker/amplifier to the signal line, a Model 00CK Connector Kit is required in each SelecTone device. Speakers designed for volt operation can connect directly to the volt output. Each message can be activated by a contact closure or opening at its associated remote control input. The remote control inputs can be configured to work with either latching or momentary contacts. -. CHASSIS DESCRIPTION. The CommCenter is assembled in a black, powdercoated steel, -piece housing. The cover is attached to the housing with four screws, two along each long edge of the enclosure. The rear of the housing incorporates two field wiring compartments baffled off from the printed circuit board area. One compartment is for the connection of the Class II power and signal lines, and the other is for the connection of the Class I power lines. These areas are provided with knock-outs to allow the external wiring to enter the unit through appropriate installer-supplied bushings. Each CommCenter can accommodate up to six storage chips, selected from a library of prerecorded voice messages, melodies, tones and/or signals. There is one message per storage chip. Each chip plugs into a -pin IC socket. The six sockets are labeled Priority Tone through Priority Tone (see figure -). KCKOUT PROVISION 0.

8 SECTION III INSTALLATION Failure to follow all safety precautions and instructions may result in property damage, serious injury, or death to you or others. SAFETY MESSAGE TO INSTALLERS Peoples lives depend on your safe installation of our products. It is important to follow all instructions shipped with the products. This device is to be installed by a trained electrician who is thoroughly familiar with the National Electric Code and will follow the NEC guidelines as well as local codes. The selection of the mounting location for the device, its controls and the routing of the wiring is to be accomplished under the direction of the Facilities Engineer and the Safety Engineer. In addition, listed below are some other important safety instructions and precautions you should follow: Although your signaling system is working properly, it may not be completely effective. People may not hear or heed your warning signal. You must reconize this fact and proceed with due caution. Read and understand all instructions before installing or operating this equipment. Do not connect or service this unit when power is on. Optimum sound distribution will be severely reduced if any objects are in front of the speaker. You should ensure that the front of the speaker is clear of any obstructions. All effective warning speakers produce loud sounds which may cause, in certain situations, permanent hearing loss. You should take appropriate precautions such as wearing hearing protection. All effective warning speakers produce loud sounds, which may cause, in certain situations, permanent hearing loss. The device should be installed far enough away from potential listeners to limit their exposure while still maintaining its effectiveness. The OSHA Code of Federal Regulations 0. Noise Standard provides guidelines which may be used regarding permissible noise exposure levels. After installation, test the sound system to ensure proper operation. Show these instructions to your Safety Engineer and all operating personnel and then file them in a safe place and refer to them when maintaining and/or reinstalling the unit. Establish a procedure to routinely check the sound system for proper activation and operation UNPACKING. After unpacking the Model 00MB, examine it for damage that may have occurred in transit. If the equipment has been damaged, do not attempt to install or operate it, file a claim immediately with the carrier stating the extent of the damage. Carefully check all envelopes, shipping labels and tags before removing or destroying them. Before attempting to install the CommCenter, be sure that all parts listed in the KIT CONTENTS LIST have been supplied. -. KIT CONTENTS. Qty. Description Part No. Plug, 0 Position 0A-0 Plug, Position 0A- -. INPUT CONFIGURATION. The CommCenter can be configured for remote activation in four ways: Normally open latching contacts. Normally open momentary contacts. Normally closed latching contacts. Normally closed momentary contacts. The unit is factory set to be activated by closing a normally open latching contact between the associated input and circuit ground. When activated the message will continue to loop and repeat. It will stop as soon as it is deactivated. When configured for momentary activation, the message will continue to loop and repeat until the input is deactivated. Upon deactivation of the input, it will play the entire message before stopping. Each of the six inputs can be individually configured by moving a two position jumper on a three position header. See table - for a list of the Priority Tones, their associated jumper designation and their marking as shown on the printed circuit board silkscreen. -. CONTROL CIRCUITRY. A. The control circuitry in the CommCenter has a built-in priority level feature. If a given message is already sounding when a higher priority message is activated, the higher priority message automatically overrides the lower priority message. When the higher priority message is deactivated, the lower priority message is initiated as long as it is still activated. The messages are prioritized with Priority Tone having the highest priority down to Priority Tone. The cascade input has the lowest level of priority.

R M configures an individual channel to interface to a latched contact (R) or a momentary contact (M). Table -. B. A message can be activated from the tone activation inputs on TB. A dry contact, either normally open or normally closed depending on the configuration, connected between the associated message (TB- through TB-) and COM (TB-) will activate a tone. The configuration of these channels is described in paragraph -. These inputs are opto coupled to reduce the possibility of noise on the signal lines falsely activating a message. C. There are two sets of contacts which can be used to monitor the status of a CommCenter. When power is applied, a relay with form C contacts is activated. These contacts are connected to TB and are labeled Power Monitor Relay. The second set of contacts monitor activation of any of the six messages or a cascaded input. These contacts are labeled Push To Talk (PTT) on TB. Do not perform any installation or maintenance to the system when power is on. -. POWER. In order to prevent power to a CommCenter from being turned off accidentally, the unit does not have a power switch. A 00MB can be operated on either 0VAC, 0/0 HZ or VDC input power. Failure to follow all safety precautions and instructions may result in property damage serious injury, or death to you or others. Do not perform any installation or maintenance on this system when power is on. This device is to be installed by a trained electrician who is thoroughly familiar with the National Electrical Code and will follow the NEC guidelines as well as local codes. The selection of the mounting location for this device, its controls, power supplied, and the routing of the wiring is to be accomplished under the direction of the facilities engineer and the safety engineer. If operation on 0VAC is desired, 0VAC is input through the -position field wiring terminal block located at the back of the unit. Two knock-out openings are provided. One knock-out should be removed and provided with a bushing through which the power lines can be routed into the field wiring compartment. The 00MB is factory set for 0VAC operation. If operation on 0VAC is desired, switch SW must be set to the 0V position. If operation on VDC is desired, VDC is input on the two terminals shown in figure -. Remove the labeled jumper from terminals TB- and TB- of terminal block TB, before using these positions. If VDC operation is chosen, a Class II power supply and its associated wiring should be installed. Refer to paragraph -.D. if the power down option is desired. -. AUDIO INPUT. There is a provision for a low level, low impedance audio signal input at the rear of the unit. It has been designed to accept a cascaded input from a slave CommCenter, TB-, but it could be audio from a telephone system, radio receiver, CD player, or tape player. When the enable pin on the cascade input is pulled to circuit ground, TB-, audio on the cascade in signal line is gated through the CommCenter and output on the signal lines. As stated before, this input is the lowest priority. The audio level input should be Vp-p. When cascading units, connect the slave unit s enable signal out terminals to the master unit s -

The SIG COM terminals (TB-) of both uinits also need to be connected together as shown in figure SIGNAL LINES. The signal lines transfer the messages from a CommCenter to the remote SelecTone devices. In order to reduce the possibility of cross talk, hum, and static noise pick-up, the signal lines must be twisted pair audio cable. In the majority of systems, use AWG twisted pair audio cables. Shielded, twisted pair cable is recommended when the Class II signal circuit is in the vicinity of welding equipment, carbon arc equipment, or similar electrical devices. Never use a cable having wire smaller than AWG. Federal Signal Corporation does not recommend that new or existing telephone lines be used as signal lines in a SelecTone system for the following reasons:. Interference from other services or systems, or interference from the system to other services.. Cross talk, interference, or hum induced by other telephone lines.. Extended downtime because of the second party involvement required to service the lines.. The additional cost of installation, interfacing devices and monthly charges as opposed to a one-time cost of performing the installation. -. MODEL 00MB SIGNAL CONNECTIONS. Mixing signal lines with power lines could cause electrical interference, which could impede or render the system inoperable. Do not install signal lines in the same conduit with power lines. To connect the signal lines of the SelecTone system to the 00MB, connect a color coded twisted pair of audio cables having conductors no smaller than AWG to SIG HI (TB-) and SIG COM (TB-) terminals on TB (see figure -). Every remote Selec- Tone signaling device in the system will be connected in parallel to these lines. When connecting the remote devices in parallel to the signal lines, observe the correct polarity and install wire nuts over the connections. The yellow wires on the 00CK should be connected to the SIG HI while the blue wires should be connected to SIG COM. The rms speaker output is available at TB- and TB- for direct connection to ceiling speakers (see figure -). Remove the labeled jumper from terminals TB- and TB- of terminal block TB, before using these positions. Signal line losses -

Both are referred to as message chips in this manual. The messages stored on pluggable circuit boards will operate on all Series B, Series C, and Series D Models. The Series D CommCenters use a different storage IC than the Series A, Series B, and Series C. These ICs cannot be interchanged between Series A, Series, B, and Series C models. Make sure to specify which series CommCenter you have before ordering any additional messages. It is necessary to perform the procedures in this section ONLY if it is required to change the priority of the storage chips or adding a different message to the unit is required. The 00MB can accommodate up to six storage chips. The CommCenter should be shipped from the factory with the storage chips installed. Each storage - chip is marked with the Model Number and other information. Failure to follow all safety precautions and instructions may result in property damage serious injury, or death to you or others. Do not perform any installation or maintenance on this system when power is on. This device is to be installed by a trained electrician who is thoroughly familiar with the National Electrical Code and will follow the NEC guidelines as well as local codes. TE The Storage Chips and the CommCenter s circuitry can be destroyed or damaged by static discharge. Observe anti-static procedures when installing or servicing a CommCenter. Storage Chips should be installed starting at Priority Tone and working downward. If, for example, only four messages are required, have PT through PT sockets occupied and leave PT and PT open. To remove a storage chip gently pry it out of its socket. To install the storage chips insert them into the desired sockets on the printed circuit board as shown in figure -. Ensure that the notch on the edge of the new storage chip is facing in the same direction as the old one (next to the resistors at the edge of the board) and that all pins are properly inserted in the socket not bent under. Test the CommCenter after any maintenance is performed.
